The Halifax Explosion occurred, resulting from a collision between the SS Mont-Blanc, carrying highly flammable and explosive materials, and the Norwegian vessel SS Imo in the Halifax Harbour. The explosion devastated the Tufts Cove and Turtle Grove areas in Dartmouth, and the Richmond and North End districts of Halifax. Two thousand people were killed, 9,000 injured and 20,000 were left homeless. Halifax’s population at that time was 55,000. (First photo: Looking south along the railway track after the explosion.
